I am trying to use my ext4 USB drive but Ubuntu 13 is currently mounting it with write permission only for root so with my normal user I can't write to it, without sudo.
The first place I checked was
dconf-editor which has the following options
and it seems to me there should be an option in there to control if I can write to the mounted USB drive, but no.
I also made sure my user is in the relevant groups:
I've searched most of the internet and can't find a solution to change the permissions given by the mount operation. There's literally nobody out there having this problem incredibly. A ton of people have issues because their drives mounts totally read-only, but not this way with only root write permission.
I can't see any way of controlling what happens. I looked at setting the mount options using
gnome-disks but drew a blank.
It's not in
fstab but it does appear in the
mount list or /etc/mtab:
/dev/sdb1 /media/adam/WDPassport2T ext4 rw,nosuid,nodev,uhelper=udisks2 0 0
This is what appears in syslog if it helps:
